Subscription Manager password. Required for RHSM Hosted. Can be optionally used for Satellite, but it may be better to use **rhsm_activationkey** for this.
-NOTE: This variable is prompted for at the start of the playbook run. This is for security purposes so the password is not left in the command history. If specified on the command-line or set in a variable file it will be ignored and the value captured from the prompt will overwrite it instead.
+NOTE: If this variable is specified on the command-line or set in a variable file it may leave your password exposed. For this reason you may perfer to use an Activation Key if using Satellite. For RHSM Hosted, your password must be specified. There are two ways to provide the password to the Ansible playbook without exposing it to prying eyes.
+
+1. The first method is to use a **vars_prompt** to collect the password up front one time for the playbook. Ansible will not display the password if the prompt is configured as **private** and the task will not display the password on the CLI. This is the a good method as it supports automating the task to every host with only one password entry. To enable **vars_prompt** add the following to the very top of your playbook after the **hosts** declaration and before any **pre_tasks** section:
+
+ ```
+ - hosts: localhost
+ # Add the following lines after a -hosts: declaration and before pre_tasks:
+ # Start of vars_prompt code block
+ vars_prompt:
+ - name: "rhsm_password"
+ prompt: "Subscription Manager password"
+ confirm: yes
+ private: yes
+ # End of vars_prompt code block
+ pre_tasks:
+ ```
+
+2. A second method is to use an encrypted file via **ansible-vault**. This does does not require modifying any code as the previous method, but does require more work to create and encrypt the file. To accomplish this, first create a file containing at least the **rhsm_password** variable (it is also possible to specify additional variables to encrypt them all as well):
+ 1. Create a file to contain the variable such as **secrets.yml**:
+
+ ```
+ ---
+ rhsm_password: "my_secret_password"
+ # other variables can optionally be placed here as well
+ ```
+
+ 2. Encrypt the file with **ansible-vault**:
+
+ ```
+ $ ansible-vault encrypt secrets.yml
+ Vault password:
+ Confirm Vault password:
+ Encryption successful
+ ```
+
+ 3. When executing **ansible-playbook** specify **--ask-vault-pass** to be prompted for the decryption password, and also specify the location of the **secrets.yml** as such:
+
+ ```
+ $ ansible-playbook --ask-vault-pass --extra-vars=@secrets.yml --extra-vars="rhsm_username=myusername" <other playbook options>
+ ```
+
+ NOTE: Optionally the file containing the encrypted variables can be decrypted with **ansible-vault** and the **--ask-vault-pass** option omitted to prevent any password prompting (for automated runs) and the file can be encrypted after the run. This can be used if an external system such as Jenkins would handle the decryption/encryption outside of Ansible.
